LJ

What LJ does

LJ Inc. is a privately held, family-owned industrial, commercial, and residential turn-key solutions company headquartered in Swartz Creek, Michigan. Founded in 2010 by Laura Slieff (with husband Tracy) as a three-person electrical contracting firm operating from a dining room table, the company has grown to more than 100 employees working out of a 35,000 sq. ft. facility and serves customers across Michigan and the broader Midwest. The corporate name evolved from LJ Electric to LJ Inc. to reflect a multi-trade expansion strategy under a single brand, "We Do That."

The company delivers a broad portfolio of technical services: electrical contracting (new construction, upgrades, MSHA-certified high-voltage work), HVAC installation and air purification, industrial turn-key services (machine repair, plant relocation, custom fabrication, rigging), automation and robotic integration (controls upgrades, cycle time enhancement, emergency on-site repair), horizontal directional drilling (1/2" to 24" diameter pipe, 30ft to 1,600ft bore shots), pipefitting (multiple joining methods and materials), millwright work including portable line boring and welding, networking/IT and computer repair, landscaping, concrete, and heavy equipment rental with or without operators. Underlying capabilities include an in-house fabrication shop with 75 years of precision machining experience, a fleet of industrial equipment (cranes from 30-90 tons, boom trucks, telehandlers, scissor lifts), and MSHA-certified electricians.

LJ generates revenue primarily through project-based, one-time engagements across residential, commercial, and industrial customer segments, supplemented by usage-based equipment rental, hardware sales of Generac generators (the company is a Generac PowerPro Elite Authorized Dealer — the top tier), and professional services for automation and robotics. Distribution is direct: phone, website contact forms (with department-specific routing), and on-site field service delivery. The wholly-owned subsidiary Supreme Manufacturing LLC supplies custom conveyor systems, storage tanks, hoppers, and dredging equipment, creating a captive manufacturing channel for industrial customers.
